Gene therapy is the use of genetic material to treat, cure, or prevent a disease or medical condition caused by a deficient or dysfunctional protein. It involves the introduction of genetic material into a target cell. The principle of gene therapy is based on the transfer of a therapeutic gene using viral (adenoviruses, adeno-associated viruses, lentiviruses, herpes viruses) or non-viral vectors as a result of which, the recepient cells will start to produce proteins that will correct a genetic disorder or acquired disease.

 


Equipments

THE VECTOROLOGY research facility comprises two rooms where users can produce or handle biological material categorised as Biosecurity Level 2 or 3 (BSL):

There are two main parts to the vectorology platform:

1. The L3 cell culture room meets all the legal requirements for the production and handling of class 2 or 3 GMO’s microorganisms. It is available for any team who wishes to make their own viral vectors for a given project.

2. The A2 room is located in the animal facility. It is where the viral vectors are tested in vivo: The viral vectors are safely administered to rodents in the A2 room. Many techniques are available to users:

  • Systemic injection ;
  • Intra-ocular injection

Gene therapy is the use of genetic material to treat, cure, or prevent a disease or medical condition caused by a deficient or dysfunctional protein. It involves the introduction of genetic material into a target cell.

The principle of gene therapy is based on the transfer of a therapeutic gene using viral (adenoviruses, adeno-associated viruses, lentiviruses, herpes viruses) or non-viral vectors as a result of which, the recipient cells will start to produce proteins that will correct a genetic disorder or acquired disease.

The viral vectors are used in the institute as a tools for transferring different genes into cells:
• Replacing a mutated gene by a healthy copy
• Gene knockdown, via tools like shRNA
• Expression of neuroprotective genes
• Expression of genetically encoded light sensitive modulators of membrane potential (optogenetics) or calcium sensors (Gamp)
• or molecules derived from a screen

Many different projects use these tools to study a broad range of subject, including neural development, tracing of neurons in the brain, replacement gene therapy, expression of optogenetic tools in targeted retinal cells, etc.
